Nen

Biodata

Four Major Principles

Applications

Combat and defense

• Nen can reinforce attacks and defenses, form shields or blades, and exert pressure strong enough to pin weaker fighters in place 62 206.
• Techniques differ by user: Netero manifests the 100-Type Guanyin, Killua uses electrical attacks, and Kurapika controls chains 21 206.
• Aura may remain active after death under particular conditions. The Immortal Champion’s Will persists as a Nen body anchored to spectators’ memories 44.

Healing and recovery

• Leorio directs Nen toward injuries and, after improving his control, can treat multiple wounded people far more efficiently 297 303.
• Nen reserves can be restored or improved by certain foods and materials, including Stardust Grass and Crystal Armor Beetle King meat 247 370.

Training and Limitations

• Control matters as much as output. Netero corrects Gon’s wasteful Ten and Ren; Shingen-Ryu breathing practice helps him steady his Nen when restless 62 63.
• Techniques can carry severe costs. Future Gon’s Forced Growth is sustained by sacrificed life and future; its collapse leaves him critically weakened 67 68.
• Nen can be suppressed or consumed. The northern ice domain accelerates its dissipation, Gray Moth drains it from attacks, and the Black Tower makes it difficult to gather 218 228 381.
• Some opponents absorb Nen outright. The Nullifier removes the aura from Gon’s full-power strike without taking lasting damage 385.
• Nen is not necessary for every extraordinary feat. Saitama cannot sense or perform basic Ten, yet his unaided punch breaks Biscuit’s Ko defense 111.
